Tube cathode protection inspection and monitoring system

Abstract

The invention relates to a tube cathode protection inspection and monitoring system, comprising a cathode protection data monitoring center, at least one first wireless intelligent telemetering terminal, and a plurality of second wireless intelligent telemetering terminals, wherein the cathode protection data monitoring center is used for receiving, analyzing and storing data sent by wireless intelligent telemetering terminals installed in a pipe network and providing an underground pipe network cathode protection system security monitoring service for a client; the at least one first wireless intelligent telemetering terminal is installed on the pipe network, is connected with a constant potential rectifier and is used for detecting U+ voltage signals, I+ current signals, RE electric potential signals and SR given potential signal parameters of the cathode protection system of the constant potential rectifier, and the plurality of second wireless intelligent telemetering terminals are installed on the pipe network, are connected with test posts and are used for detecting the cathode potential and power-failure potential parameters of the test posts. The tube cathode protection inspection and monitoring system provided by the invention is mainly used for solving the technical problems that the manual poling labor intensity is large, the cost is high, and the poling precision is low; according to the tube cathode protection inspection and monitoring system, the stray current influence and electromagnetic interference on an underground pipe network can be eliminated, and the U+, I+, RE and SR parameters of the cathode protection system can be immediately, correctly and completely monitored.

Description

technical field [0001] The invention relates to a detection and monitoring system for pipeline protection with wireless transmission function, in particular to a pipeline cathodic protection detection and monitoring system. Background technique [0002] The city gas industry is one of the key development industries during the 12th Five-Year Plan. Under the environment of controlling greenhouse gas emissions, city gas as a clean energy is increasingly widely used in large and medium-sized cities. The safety of the underground pipeline network for transporting city gas is also receiving increasing attention. Anti-corrosion using cathodic protection technology is a necessary measure to ensure the safety of urban gas underground pipeline network. The protection effect depends on timely, correct and complete detection of cathodic protection system U+ voltage signal (V), I+ current signal (A), RE potential signal (mV ), SR given potential signal (mV) and other parameters. The tr...
